OK, after doing some reading about insulin spikes, I have a question. Some feel they obtain better results by dividing their meals into pro/fat and pro/carb. Could someone give me a scientific explanation as to why the body will store more fat when carbs and fat are eaten together?

Also, probably a dumb question but I've read you need healthy fats to burn fat. Explanation? I'd just like some detailed responses so I can hold this knowledge for myself and relay it to others when asked for advice. I'm trying to expand my knowledge on nutrition/dieting and I like to know exactly WHY food and the body do certain things. Thanks for any help!
